widening with a flattened spine at one of its angles and a slen- 

 der branch near the base. Harpes broad, inner edge thickened, 

 curving at tip and ending in a few teeth ; moderately long and 

 slender hairs present on one margin. Unci forming a basal 

 cone. Basal appendages low, each bearing four or three small 

 hairs. 



Genus JOBLOTIA Blanchard 



Joblotia compressum Lutz. 



Hypopygium. Side pieces conical, over twice as long as 

 wide ; at the base a rounded lobe is present, with long setae 

 reaching to tip of side piece. Clasp filament long and slender 

 with an inserted subterminal double claw. Harpes flat, slender, 

 with bent tip. Basal appendages widely separated, each with 

 about ten long setse. 



Genus GOELDIA Theobald (1903) 



The genera Isostomyia Coquillett (1906), Binotia Blanchard 

 (1904), Hyloconops Lutz (1907), Lesticocampa Dyar and 

 Knab (1906) become synonyms of Goeldia Theobald (1903), 

 as will be shown below. Runchomyia Theobald (1903) was 

 preoccupied. For the synonymy of Lesticocampa Dyar and 

 Knab, we refer to Howard, Dyar and Knab (Mosq. N. & C. 

 Amer. & W. Ind., iii, 163, 1915). 



Goeldia lunata Theobald. 



The head of the type of Wyeomyia lunata Theobald, a fe- 

 male, is missing. The scutellum is concolorous with the meso- 

 notum. Several other specimens, all from Rio, put here by 

 Theobald have the clypeus nude and also the scutellum con- 

 colorous with the mesonotum. Amongst them is a male, the 

 genitalia of which we mounted. We do not see differences 

 with the genitalia of Lesticocampa rapax Dyar and Knab, 

 only the tip of the side piece is rounded, not conical. This 

 male has long palpi like rapax. The proboscis of this species 

 is very long and pointed. A complete description of the male 

 genitalia is as follows: Side pieces twice as long as wide, tips
